Title: Method and instrument for measuring dc voltage
Inventor: KUROSAWA KIYOSHI
IPC: G01R19/00
Filed: 1993-12-02
Abstract: PURPOSE:To suppress the drop of an optical output with time (drift) without making the constitution of a DC voltage measuring instrument more complicated by transforming light from a light source into elliptically polarized light through a vertical Pockels element after transforming the light into circularly polarized light. CONSTITUTION:When the light emitted from a light source 1 is transmitted to an optical voltage detector 3 through an optical fiber 2, the light is transformed into prescribed linearly polarized light through a polarizer 7 and further transformed into circularlly polarized light through a quarter wave plate 8. The circularly polarized light becomes the elliptically polarized light corresponding to a voltage V to be measured when the light is passed through a vertical Pockels element 11. An analyzer 10 detects major-axis polarized light and ntinor-axis polarized light and transmits the detected major- and minor-axis polarized light rays to photoelectric converters 5A and 5B through optical fibers 4A and 4B, respectively. The converters 5a and 5B output the polarized light rays to an arithmetic device 6 as major- and minor-axis polarized light signals A and B after photoelectric conversion and the device 6 calculates the DC voltage V by calculating (A-B)/(A+B) from the input signals A and B.

Filed: 1992-12-25
Abstract: PURPOSE:To facilitate the oriented growth of a ferroelectric thin film on a semiconductor single crystal substrate by a method wherein a double-layer structure composed of a buffer thin film and a metal thin film is formed on the semiconductor single crystal substrate. CONSTITUTION:An epitaxial layer is formed on a GaAs substrate 1 (zinc blend structure) by an excimer laser deposition method wherein the excimer laser is applied to a target surface. Metal Mg is employed as target material. O2 is introduced during a film forming process and oxidize Mg to form an MgO thin film 2 (NaCl structure). An n-type GaAs wafer is employed as the GaAs substrate 1. After the wafer is washed with solvent, the wafer is etched with H2SO4 system solution. After the wafer is rinsed with deionized water and ethanol, the wafer is subjected to spin drying with ethanol under a nitrogen gas flow. Then a Pt thin film 3 (face-centered cubic structure) is built up on the MgO thin film 2 by epitaxial growth. Further, a PbTiO3 thin film 4 (perovskite structure) is formed on the Pt thin film 3 by oriented growth. This double-layer structure helps the epitaxial growth of the ferroelectric thin film and, further, as it functions as a diffusion barrier, the oriented growth of the ferroelectric thin film on the substrate can be realized.
